FIG. 2.
Influence of different concentrations of atrazine on growth of A. aurescens TC1. Strain TC1 was grown in minimal medium using atrazine as a sole source of carbon, nitrogen, and energy. (A) Culture grown with 500 mg of atrazine per liter (□) and culture initially grown on 500 mg of atrazine per liter and receiving an additional 500 mg of atrazine per liter at the time indicated by the arrow (▪); r2 = 0.90. (B) Linear correlation of growth of A. aurescens TC1 on several concentrations of atrazine; r2 = 0.99.
